摘要(Abstract):

为了提高末页岩低温热解效率,以甘肃窑街末页岩为研究对象,采用管式加热炉,研究不同热解终温、终温恒温时间、热载气体流量等热解条件对甘肃窑街末页岩热解产油率的影响。结果表明:末页岩随热解温度升高,产油率先增大后减小,540℃热解产油率达到7.95%;增加终温恒温时间,可提高产油率,恒温时间超过30 min末页岩热解产油率增大不再明显;热载气体流量增大,有利于热载气体对页岩油的携带,载气流量超过300 m L/min热解产油率趋于稳定。最优热解试验条件下原料单独热解的产油率、产水率、产气率比铝甑试验的产率有所提高。
In order to improve the efficiency of low temperature shale pyrolysis,powder shale from Yaojie of Gansu province was chosen as the research object.Using the tube type heating furnace investigated the influence of productive rate of oil solution on different pyrolysis temperature,temperature holding time,and heat carrier gas flow.The experimental results show that the increasing of pyrolysis temperature give rise to the productive rate of oil first increased and then decreased,the fastest pyrolysis rate reached 7.95% at 540 ℃.Increasing the temperature of the thermostatic time,the oil production rate is improved.Keeping temperature more than 30 min,the pyrolysis oil production rate increase is not obvious.Increasing the gas flow is conducive to carrying of shale oil.When the gas flow rate gets more than 300 mL/min of pyrolysis,oil production rate tends to be stable.At the optimum experimental conditions of raw materials,oil production rate,water production rate and gas production rate are more than the result of carbonization test in aluminium retort.
